    Gramineae, E. Launert. Flora Zambesiaca 10:1. 1971

    Habit
    Perennial, up to 70 cm. high, caespitose.
    Culms
    Culms erect, simple, glabrous or slightly scaberulous, 2-3-noded; nodes glabrous, smooth.
    Leaf sheaths
    The lowermost leaf-sheaths compressed and keeled, strongly nerved, the upper ones subterete, slightly keeled, scaberulous, tight, sometimes slightly gaping at the apex.
    Ligules
    Ligule a short ciliate rim; auricles shortly pubescent and with a few long hairs.
    Leaf lamina
    Leaf-laminae up to 8 cm. long, rather stiff, flat with inrolled margins, conduplicate or convolute, obtusely pointed, with prominent white midrib and marginal nerves, scaberulous or puberulous above, glabrous and smooth beneath.
    Inflorescences
    Panicle 10-15 cm. long, long-exserted, with a glabrous, smooth axis; branches 1-6 cm. long, very distant, solitary or 2-nate, at first erect, afterwards more or less spreading, naked in the lower 1/2, scaberulous or minutely pubescent, with shortly pubescent glandular patches in the axils.
    Spikelets
    Spikelets reddish-green to yellowish-green, densely congested, imbricate, forming small, elongate, spiciform panicles at the ends of the branches.
    Glume
    Glumes unequal, linear or nearly lanceolate; the inferior 9-10 mm. long, 1- or nearly 3-nerved (with short lateral nerves), minutely pubescent on the back and scabrid on the keel, gradually tapering into a mucro; the superior 6-8·5 mm. long, 1-nerved, smooth on the keel, slightly scaberulous towards the apex.
    Lemma
    Lemma 5-5·5 mm. long, fusiform, slightly keeled, glabrous, smooth at the base, with rows of scabridules towards the apex, slightly tapering upwards but scarsely beaked; callus c. 5 mm. long, very obtuse, densely long-barbate; column absent; awns slightly unequal, erect, scabrous; the central awn 8-11 mm. long, the lateral ones slightly shorter; articulation absent.
    [GB]
    Habit
    Perennial; caespitose. Culms erect; 30-70 cm long; 2-3 -noded. Culm-internodes distally glabrous. Ligule a fringe of hairs. Leaf-blades conduplicate, or convolute; 4-8 cm long; 0.5-1 mm wide. Leaf-blade surface scaberulous; rough adaxially. Leaf-blade apex obtuse.
    Inflorescences
    Inflorescence a panicle. Panicle open; elliptic; 10-15 cm long; with spikelets clustered towards branch tips. Primary panicle branches appressed, or spreading; distant; 1-2 -nate; 1-6 cm long. Panicle branches glandular (in axils); pubescent; pubescent in axils. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 9-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5 mm long; bearded; obtuse.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 9-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5 mm long; bearded; obtuse.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume linear; 9-10 mm long; 1.2-1.5 length of upper glume; membranous; 1-keeled; 1-3 -veined. Lower glume primary vein scaberulous. Lower glume surface puberulous. Lower glume apex acuminate; mucronate. Upper glume linear; 6-8.5 mm long; 1.2-1.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface asperulous; rough above. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic; subterete; 5-5.5 mm long; coriaceous; keeled; 3 -veined. Lemma surface scaberulous; rough above and in lines. Lemma margins involute; covering most of palea. Lemma apex acuminate; awned; 3 -awned. Principal lemma awn 3-branched; with 8-11 mm long limb; persistent. Lateral lemma awns 7-10 mm long; subequal to principal, or shorter than principal. Palea 0.2 length of lemma; without keels.
